Maybe it is a coincidence, for sure I'm not running out of memory when it is happening and started with kernel 4.15 and (or) Mesa 18.0 without any change on Virtualbox side. I'll wait for the fix to see what happens...
Well the message means that we ran out of memory to allocate a 2MB block and instead use many small 4K blocks.
I am getting these messsages on my machine right now, too.

There is enough RAM left to allocate a 2 MiB block.
